Can Windows 11 cause BSoD?
After installing the Insider build version of the Windows 11 OS in the beginning, many users have been facing different issues including the BSoD error.
With the launch of Windows 11, Microsoft renamed it the Black Screen of Death instead of the usual Blue Screen of Death.
However, Microsoft soon changed the screen color to blue when the PC fails to boot up or when there’s a stop error as in previous versions of Windows.
The Black Screen of Death error message may usually appear after connecting a new piece of hardware like a USB drive, graphics adapter, etc.
In some cases, you may also encounter TCPIP.sys BSoD error on Windows 11 due to a third-party antivirus, and hence, disabling the software could help fix the issue.
However, if you encounter any other Black Screen of Death on your PC, do let us know in the comments box below.
